HELPS Word-studies

5442 phylássō (akin to 5441 /phýlaks, "a military guard") – properly, preserve by "having an eye on" (J. Thayer), referring to the uninterrupted vigilance shepherds show in keeping their flocks (see Lk 2:8, used with 5438 /phylakḗ, "a military guard," i.e. exercising unbroken vigilance as a military guard).

5442 /phylássō ("keep watch over, keep secure") emphasizes the needed vigilance to keep what is entrusted. Thus 5442 (phylássō) is often used in the NT in the Greek middle voice meaning, "Personally be on guard against," stressing the constant, personal interest involved with the guarding.

[Examples: Lk 12:15, "Beware of," (RV, "Keep yourselves from," cf. Ac 21:25); 2 Tim 4:15, "Be thou aware" (see Vine, Unger, White, NT, 65).]
